Peach tree named ‘Supechseventeen’

ABSTRACT

A new and distinct peach tree variety,  Prunus persica,  cv. ‘Supechseventeen’ is characterized by fruit with large size, dark over-color and an early harvest.

Latin name of the genus and species claimed: Prunus persica.

Variety denomination: ‘Supechseventeen’.

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to the discovery and asexual propagation of a newand distinct variety of peach, Prunus persica cv. ‘Supechseventeen’. Thenew variety was first hybridized in 2001 and selected in 2003 by TerryBacon as breeder number: ‘PE386’. The new variety was first evaluated byTerry Bacon near Wasco, Calif. in Kern County. The variety‘Supechseventeen’ was originated by hybridization.

The new variety ‘Supechseventeen’ is characterized by its large size,dark over-color and early harvest.

The seed parent is ‘Supechsix’ (the subject of U.S. Plant Pat. No.11,631), and the pollen parent is ‘91-006C’ (an unpatented Sun Worldpeach). The parent varieties were first crossed in February 2001, withthe date of planting of the progeny being February 2002, and the date offirst flowering being February 2003. The new peach variety‘Supechseventeen’ was first asexually propagated by Terry Bacon nearWasco, Kern County, Calif. in January 2005, by budding.

The new variety ‘Supechseventeen’ is distinguished from its seed parent,‘Supechsix’, in that the fruit of the new variety ripens about five dayslater than that of ‘Supechsix’ and has darker over-color. The fruit ofthe new variety ‘Supechseventeen’ is larger in diameter than that of‘Supechsix’, at about 65 mm in comparison to 64 mm.

The fruit of the new variety ‘Supechseventeen’ is distinguished fromthat of its pollen parent, ‘91-006C’, in that the fruit of the newvariety ripens about four days later than that of ‘91-006C’ and hasmelting flesh while the fruit of ‘91-006C’ has non-melting flesh. Thefruit of the new variety ‘Supechseventeen’ is also larger in diameterthan that of ‘91-006C’, at about 65 mm in comparison to 63 mm.

The fruit of the new variety ‘Supechseventeen’ ripens at nearly the sametime as that of ‘Super Rich’ (U.S. Plant Pat. No. 9,860), but is largerin size at about 65 mm in comparison with 63 mm of ‘Super Rich’. Thefruit of the new variety also has darker over-color than that of ‘SuperRich’. The fruit of the new variety is also similar in appearance andshape to the fruit of ‘Crimson Lady’ (U.S. Plant Pat. No. 7,953), butits harvest starts about 20 days earlier.

The new variety ‘Supechseventeen’ has been shown to maintain itsdistinguishing characteristics through successive asexual propagationsby, for example, budding.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photographic illustration shows typical specimensof the foliage and fruit of the present new peach variety‘Supechseventeen’. The illustration shows the upper and lower surface ofthe leaves, exterior views of the fruit and the pit, and a sectionalview of a fruit divided across its suture plane to show flesh color, pitcavity and the stone remaining in place. The photographic illustrationwas taken shortly after the fruit was picked (shipping ripe) and thecolors are as nearly true as is reasonably possible in a colorrepresentation of this type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout this specification, color names beginning with a small lettersignify that the name of that color, as used in common speech is aptlydescriptive. Color names beginning with a capital letter designatevalues based upon The R.H.S. Colour Chart published by The RoyalHorticultural Society, London, England.
